Don't forget Joyce that ACD's think they are the biggest dog in the world when it comes to protecting you, your house, your car, etc. They are NOT a breed for the first time dog owner or ones who haven't owned a high drive herding breed, working dog etc. They need a firm owner who won't take any of their sh!t and you always need to be one step ahead of them. They are tough, stubborn, and can be very over-bearing with their owners, trying to walk all over you! LOL!
